,21,10 all' whom it may concern:

`citizenof the United States, and a resident.

`ofBethlehem, in the county of Northampton-v and State of Pennsylvania, have inl and useful improvespecific'ation rlhis invention relates to certain new and useful improvements in .valves for use in pumps, etc., :onstruetion of the upper plate and to the imanner of securing a i'ei'iewable rubber seat or seats thereto. l

The object 'of the invention is to provide a sure valve in the pumping engines of city water works,"such pressure being from 8O to inch, and at the same time provide a valve of rubber or vother suitable material which will be durable and easy of economical renewal. p In the preferred embodiment of myl invent-ion I employ two rings madeof rubber or Vother suitable material which are held in place by means 'nrmly clasping the two thin rubber ring seats or facings. The combination of the plate, the flanged nut, and'intervening materials forms a truss or deep girder-like conlstruction Which brings strength, thus giving durability and at the same time making economic renewals possible.

With this brief statement, 'my invention ma be said to lconsist of a valve as shown in its preferable embodiment in the accoin.
